DESCRIPTION  
The SP331 is a programmable RS-232 and/or RS-485 transceiver IC. The SP331 contains four  
drivers and four receivers when selected in RS-232 mode; and two drivers and two receivers  
when selected in RS-485 mode. The SP331 also contains a dual mode which has two RS-232  
drivers/receivers plus one differential RS-485 driver/receiver.  
The RS-232 transceivers can typically operate at 230kbps while adhering to the RS-232  
specifications. TheRS-485transceiverscanoperateupto10MbpswhileadheringtotheRS-485  
specifications. The SP331 includes a self-test loopback mode where the driver outputs are  
internally configured to the receiver inputs. This allows for easy diagnostic serial port testing  
without using an external loopback plug. The RS-232 and RS-485 drivers can be disabled  
(High-Z output) by controlling a set of four select pins.
